Abstract: Methods and systems for monitoring and determining a propulsion request are described. In one example, the propulsion request is evaluated according to two separate plausibility checks. The plausibility checks may include comparing a monitor propulsion request against the propulsion request and comparing the monitor propulsion request against a wheel torque.

Abstract: A system and method for controlling torque in a hybrid electric vehicle. The system provides a regenerative braking torque with an electrical machine when a level of braking torque indicated by actuation of a brake control device exceeds a level of traction torque indicated by actuation of an acceleration control device. The regenerative braking torque is supplemented by a friction braking system when the braking torque requested by a vehicle operator exceeds a maximum regenerative braking capacity of the electrical machine.

Abstract: A hill holding function of a hybrid electric vehicle is initiated when the powertrain control module determines that a hill holding condition exists. In the hill holding condition, the electro-hydraulic brakes will provide brake torque to each wheel and the powertrain control module will turn off the internal combustion engine. The system can also detect a two footer condition where the vehicle operator requests both acceleration torque and brake torque simultaneously. The hill holding function of the hybrid electric vehicle in a two footer situation will apply the electro-hydraulic brakes and turn off the internal combustion engine. When the operator requests acceleration in either the hill holding or the two footer condition, the electric brake controller will transition the release of the electro-hydraulic brakes and the powertrain control module will turn on the internal combustion engine.
